I would second the advice in daleif's answer: specifically, using \substack and using \Biggl, \Biggr, \biggl, \biggr, etc. when appropriate to help make the expression easier to read. (I would add: using the spacing commands \!, \,, \:, and \; to improve the space to keep things from being too cluttered or too offset.) The following example is meant to suggest useful practises in (a) typesetting such expressions, and (b) formatting mathematics to keep it easy to read.

Thanks a lot, my apologies about the wrong title and description.

Did you try with \biggl (or \biggr) all around? Possibly adding some space after the opening bracket.

@egreg: I didn't actually. With the \max there I would prefer myself to have the huge brackets; though I would personally choose to avoid having an expectation of a maximum with so many conditions.

@NieldeBeaudrap I tried; there's no reason for the brackets to fully enclose the subscript to \max. The white space at the top is surely worse.

@egreg: After some consideration I've edited the answer, because while I'm not convinced that the result with \Biggl and \Biggr in the outer parens looks much better, it certainly does better illustrate the point of the answer: how to pick and choose your delimiter sizes.
